If you get an answer wrong, please keep selecting other options to reveal the correct answer and explanation (if it is available). You should be able to score at least 95% (if not, go back and study your notes) because the scoring algorithm is: # right answers – # of attempts / # of questions answered * 100. So even in the middle of the quiz, you will be able to grade yourself on how well you did up that point without completing the entire quiz.

Since, Dr. Georgescu decided to repeat some of the questions from the first two midterms, some questions posted on this quiz may also have appeared on the previous 491 quizzes. However, please study the BlackBoard questions for previous exam questions.
In case in you have missed the additional support materials, please visit the main Exams & Resources page and check under GLGY 491. Note: No questions from the two midterms are posted here. But there will be some questions from them on the final. Refer to previous 491 exams.
Quick… save the world!
The world is about to get hit by a meteorite. The computer that controls the high intensity electron beam (use for destroying the extraterrestrial objects) has been hijacked by Graptolites. But they got a riddle for you. What are their orientation from I to VII? If you name them in 30 seconds or less, you may be able to save the world (Disclaimer: Probably of saving the world is a function of the power of the electron beam and it is inversely related to the time in which it take you to shoot it. In other words, the longer your take, 1/t will result in unfavorable outcomes. Once the riddle is solved, you will be granted with the access code. However, use it wisely!).
